Looking for a To-do list / Taskmanager type of app

I'm looking for a To-do list / Taskmanager type of app which allows me to make several lists but assign one of them to the apps icons badges.
As I'm switching to iPhone 5 soon it would be great if it either supported the new resolution or the app is regularly updated and thus expected to in the near future.

Reminder is the English name for the official Apple app I guess? That app is simple and would be perfect for me IF I could set one of my lists to show badges. I just need the badges number as it motivates me to decrease it...

The standard Apple Reminders app does show badges. If yours doesn't go into Settings -> Notifications and make sure badges is turned on for the Reminders app.
